With the boom arm installed you lose the sub-par ability to wrap the cord up well enough for transport, IMO. I'm sure if a spacer was put in between where the cord holders go back on you could make it work. I have seen it here somewhere before, not the hose reel idea though. I am in the process of making a hose reel out of a cable reel that was used on a deck project that I did earlier this summer. New they are $75.00 and up and it's looking promising with a couple of holes, a broken broom handle shaft, and some scrap ply. I was hoping to mount it to an air compressor cart and will post if it comes out well, Eric
